Abstract

The feedback vibration control of thin-walled beam cantilevers exposed to an external blast was discussed. The beam model features transverse isotropy of constituent material layers, the surface isotropy being parallel to the beam reference surface and transverse shear effects. The implication of effects, which include those related to the size and location of piezoactuators and the type of pressure pulse were also discussed. It was found that a constraint voltage reduces the dynamic response for a certain tine interval, after which the response starts to increase.
